是否可以在Chrome打包的应用中执行JavaScript文件？

Question

I am trying to make a Box2D TestBed structure in a Chrome app using kripken's Box2D.js . I have successfully gotten the testbed built and working you can download it from here . One of the features I would like to add to the testbed is the ability to load JavaScript files at runtime. Since chrome apps can't use eval is there any way of loading a JavaScript file at runtime? I've tried using $.getScript with a file:/// URL and the appropriate permissions but that doesn't work. Here are some example files that I would like to load at runtime. This is very frustrating since the program can be run on the web but not in a chrome app!

UPDATE:

I've tried using a chrome sandbox to do the evaling but I cannot pass functions through window.postMessage . I'm beginning to lean towards hosting it on a server.

Thanks!

You should be able to load external scripts. There's a catch though; you'll have to do it in a sandboxed page that doesn't have any access to the chrome.* APIs. But you can communicate with this page through window.postMessage

See http://developer.chrome.com/apps/app_external.html
